The video industry in Nigeria has developed within a widely informal economic environment in which the illicit reproduction and circulation of goods were the rule rather than the exception. The informality of circulation has played a particularly influential role in both the history of the video industry and the genesis of the present crisis. While, on the one hand, it has made videos available all over the African continent and within the diaspora, creating the basis for Nollywood’s international success, it has, on the other hand, weakened the industry’s economy, exposing it to consecutive cycles of saturation and collapse. For this reason, the production crisis that emerged over the past few years has catalyzed numerous controversies concerning the structure of the video economy and the rules that regulate it. The informality on which the video economy has been based since its inception is today often considered a threat to the survival of the industry itself. While the industry has achieved global recognition, the economic fragility of its success has provoked growing anxiety. This anxiety has been progressively concentrated, by both media and video entrepreneurs, on issues of piracy and copyright protection. The aim of this chapter is to investigate the causes of this anxiety and the role that piracy and transformations in copyright legislation have had in catalysing it, while shaping the economy of the industry. Throughout this chapter I will argue that when the uncontrolled circulation of goods begins to undermine the economic basis of the industry that produces them, the rhetoric of piracy is mobilized to ensure the accessibility to the economy of both the production and the distribution of the goods themselves. This allows some of the entrepreneurs involved in the production process to gain exclusive control over it and the capital it generates. Within the Nigerian context, the rhetorical construction of piracy and the legal and economic consequences of this construction are the result of specific conflicts among different segments of the Nigerian video industry and, more precisely, different models of economic entrepreneurship. As the history of the Nigerian video phenomenon shows, a loose copyright regime seems to have positive consequences for the emergence and early development of a creative industry, although, once the industry seeks to attain higher levels of profitability, it tends to become problematic, and the rhetoric of piracy can become a tool to orient processes of restructuration of the cultural industry’s economy. In relation to this dynamic, I analyse the way in which the normative orders that regulate the reproduction and circulation of images and contents developed within the Nigerian context, and I discuss how their introduction and implementation progressively shaped people’s perception of legal and illegal practices in the field of local cultural production.

Introduction Adherence to therapy is a relevant challenge in chronic hemodialysis patients. The directly observed therapy (DOT) could be an effective method to increase adherence for specific therapies. We aimed to study the performance of DOT versus home medication. We follow the impact of providing native vitamin D directly by the nurse after a dialysis session on the 25-hydroxyvitamin [25(OH)D] concentrations. Methods In this observational study, we included 38 dialysis patients treated by stable dosage of cholecalciferol. DOT was implemented in December 2010. We considered the concentrations of 25-OH vitamin D three times before (T1 = June 2010, T2 = July 2010 and T3 = September 2010) and three times after the modification of prescription (T4 = February 2011, T5 = March 2011 and T6 = April 2011). Results Median age was 72 [62; 79] years and 48 % were diabetics. Mean body mass index was 26 ± 5 kg/m2 and median dialysis vintage was 20 [8; 46] months. The patients were compared to themselves. Before DOT, median concentrations of 25(OH)D were 27 (14–36), 23 (17–31), 31 (22–38) ng/mL at T1, T2 and T3, respectively. When DOT was effective, the concentrations significantly increased to 34 (28–44), 35 (29–41), 39 (32–47) ng/mL at T4, T5 and T6, respectively. Before DOT, 19 patients (50 %) reached the target of 30 ng/mL. After DOT, 29 patients (76 %) reached the target concentration of 30 ng/ mL. Conclusions In hemodialysis patients, DOT is both simple and effective to increase the therapeutic impact to native vitamin D. [less ▲]

In the fight against terrorism States have resorted to a variety of weapons. Much attention has been devoted to criminal law as a possible answer to terrorism. Many States have also resorted to nationality law, using deprivation as a means to punish those involved in terrorism. This paper will focus on Belgium and France. These two countries indeed present striking similarities. Both in France and Belgium the provisions on deprivation already made it possible to deprive a national of his citizenship in terrorist cases. Nevertheless, the legislation in these countries has been recently modified to offer yet a stronger answer to terrorism. The public debate in the two countries is modelled on similar lines. This is in particular true for the issue of equality arising in connection of deprivation of nationality. The paper will first offer an overview of the existing statutory provisions in the two countries, before critically reviewing the discussion on equality and non discrimination. [less ▲]

We present a thorough investigation by magneto-optical imaging of the magnetic flux penetration in Nb thin films with lithographically defined border indentations. We demonstrate that discontinuity lines (d-lines), caused by the abrupt bending of current streamlines around the indentations, depart from the expected parabolic trend close to the defect and depend on the shape and size of the indentation as well as on the temperature. These findings are backed up and compared with theoretical results obtained by numerical simulations and analytical calculations highlighting the key role played by demagnetization effects and the creep exponent n. In addition, we show that the presence of nearby indentations and submicrometer random roughness of the sample border can severely modify the flux front topology and dynamics. Strikingly, in contrast to what has been repeatedly predicted in the literature, we do not observe that indentations act as nucleation spots for flux avalanches, but they instead help to release the flux pressure and avoid thermomagnetic instabilities.

Très répandues dans le règne végétal, les anthocyanes sont le sujet d'un grand nombre d'études. Celles-ci abordent en général les aspects concernant leur instabilité vis-à-vis des conditions dans lesquelles elles sont employées ou l'effet bénéfique de leur consommation sur certaines pathologies chroniques. Provenant de nombreux types de fruits et légumes comestibles, elles sont extraites en vue de leur utilisation comme colorant alimentaire naturel. C'est ce dernier aspect qui a été le sujet principal de ce travail dont l'objectif était de montrer que les calices d’Hibiscus sabdariffa (H. sabdariffa) pouvaient être utilisés comme matière première pour la fabrication de colorant. Les deux principaux cultivars provenant du Sénégal présentent des différences significatives du point de vue de leur contenu en anthocyanes sur le plan qualitatif et quantitatif. L'influence des conditions de culture sur la concentration en anthocyanes a été mise en évidence. Une technique chromatographique a été utilisée pour concentrer les anthocyanes. Les résultats provenant d'expériences faites en batch agité avec une résine macroporeuse ont permis de déterminer les paramètres tels que le temps de contact nécessaire à l'atteinte de l'équilibre, la capacité d'adsorption maximale et de conclure que la résine utilisée avait une capacité d'adsorption élevée pour les anthocyanes. Suite à la fabrication du colorant, une partie importante de la masse de calices restait inutilisée alors qu'elle contenait encore des substances valorisables. Leur caractérisation a permis de montrer que les résidus des calices d'H. sabdariffa pourraient être valorisés par la production de pectines destinées au marché des additifs alimentaires, d'oligosaccharides à effet prébiotique ou de biocarburants.

Cupressus sempervirens est l’une des espèces les plus répandues en Algérie ayant une capacité allergénique très élevée. Nous avons étudié,d’abord, comment l’instillation nasale des différentes fractions de l’extrait pollinique de cette espèce peut moduler la réponse immunitaire chez les souris, et, ensuite, la stimulation des cellules épithéliales bronchiques humaines (BEAS-2B) par l’allergène majeur, identifié par spectrométrie de masse et purifié par chromatographie échangeuse d’ions. La sensibilisation des souris a révélé, d’une part, une diminution du nombre de neutrophiles et une augmentation des éosinophiles, et, d’autre part, une augmentation significative du total cellulaire dans le liquide du lavage bronchoalvéolaire.L’étude histologique des poumons a montré une présence d’infiltrat inflammatoire et d’oedème péri-bronchique. La spectrométrie de masse nous a permis de mettre en évidence la présence de l’allergène majeur Cup s 1 dans toutes les fractions avec une présence spécifique du Cup s 3 et Cupa 1 dans la fraction 4.

Dairy products provide a package of essential nutrients that is difficult to obtain in low-dairy or dairy-free diets, and for many people it is not possible to achieve recommended daily calcium intakes with a dairy-free diet. Despite the established benefits for bone health, some people avoid dairy in their diet due to beliefs that dairy may be detrimental to health, especially in those with weight management issues, lactose intolerance, osteoarthritis, rheumatoid arthritis, or trying to avoid cardiovascular disease. This review provides information for health professionals to enable them to help their patients make informed decisions about consuming dairy products as part of a balanced diet. There may be a weak association between dairy consumption and a possible small weight reduction, with decreases in fat mass and waist circumference and increases in lean body mass. Lactose intolerant individuals may not need to completely eliminate dairy products from their diet, as both yogurt and hard cheese are well tolerated. Among people with arthritis, there is no evidence for a benefit to avoid dairy consumption. Dairy products do not increase the risk of cardiovascular disease, particularly if low fat. Intake of up to three servings of dairy products per day appears to be safe and may confer a favourable benefit with regard to bone health. [less ▲]

The mechanisms of Li+ insertion in porous hard carbons used as anodes for Li-ion batteries are still a matter of debate, especially considering the divergence of electrochemical performances observed in literature. Since these materials usually exhibit several levels of porosity, the pore texture vs. electrochemical behavior relationship is difficult to establish. In this paper, we propose to use carbon xerogels, prepared from aqueous resorcinol-formaldehyde mixtures, as model materials for Li-ion battery anodes to study the influence of the pore texture on the overall electrochemical behavior. Indeed, carbon xerogels are described as microporous nodules linked together to form meso- or macroporous voids inside a 3D gel structure; the size of these voids can be tuned by changing the synthesis conditions without affecting other parameters such as the micropore volume. The materials are chosen so as to obtain identical average particle sizes, homogeneous coatings with similar thicknesses and a comparable surface chemistry. The electrochemical behavior of carbon xerogels as Li-ion anodes are correlated with the surface accessible to the electrolyte and are not dependent on the total specific surface area calculated by the BET method from nitrogen adsorption isotherms. The key parameter proposed to understand their behavior is the external surface area of the nodules, which corresponds to the surface of the meso/macropores. [less ▲]

Two methods were assessed for the generation of common N heterocyclic carbenes (NHCs) from stable imidazol(in)¬ium precursors using convenient and straightforward continuous-flow setups with either a heterogeneous inorganic base (Cs2CO3 or K3PO4) or a homoge¬neous organic base (KN(SiMe3)2). In-line quenching with carbon disulfide revealed that the homogeneous strategy was most efficient for the preparation of a small library of NHCs. The generation of free nucleophilic carbenes was next telescoped with two benchmark NHC-catalyzed reactions, namely, the transesterification of vinyl acetate with benzyl alcohol and the amidation of N-Boc-glycine methyl ester with ethanolamine. Both organocatalytic transfor¬ma¬tions proceeded with total conversion and excellent yields were achieved after extraction, showcasing the first examples of continuous-flow organocatalysis with NHCs.

Given the potential of peptide selenoesters for protein total synthesis and the paucity of methods for the synthesis of these sensitive peptide derivatives, we sought to explore the usefulness of the bis(2-selenylethyl)amido (SeEA) group, i.e. the selenium analog of the bis(2-sulfanylethyl)amido (SEA) group, for accelerating peptide bond formation. A chemoselective exchange process operating in water was devised for converting SEA peptides into the SeEA ones. Kinetic studies show that SeEA ligation, which relies on an initial N,Se-acyl shift process, proceeds significantly faster than SEA ligation. This property enabled the design of a kinetically controlled three peptide segment assembly process based on the sequential use of SeEA and SEA ligation reactions. The method was validated by the total synthesis of hepatocyte growth factor K1 (85 AA) and biotinylated NK1 (180 AA) domains [less ▲]
